Novel anti-rust oil and preparation method thereof

Abstract

The invention relates to the field of oil solvents, in particular to novel anti-rust oil and a preparation method of the novel anti-rust oil. In allusion to the problems that existing anti-rust oil is poor in anti-rust performance and film-forming stability during use, poor in corrosion inhibition, high in viscosity and poor in film-forming quality, the invention proposes the following scheme: the novel anti-rust oil comprises the following raw materials in parts by weight: 70-85 parts of base oil, 8-14 parts of a composite corrosion inhibitor, 5-7 parts of an alkaline solution, 2-5 parts of paraffin, 20-35 parts of a diluent, 20-35 parts of butyl cellulose, 1-3 parts of a film-forming agent and 1-2 parts of an antioxidant. The alkaline solution is doped to improve the anti-rust performance; the composite corrosion inhibitor is doped to improve the corrosion inhibition strength so as to enhance the anti-rust effect; the paraffin is doped to enhance the film-forming stability when the anti-rust oil is used; and by doping the diluent, the anti-rust oil has the characteristic of low viscosity and is easy to coat, the consumption of the anti-rust oil is reduced, and by cooperatively doping the butyl cellulose, the anti-rust oil is good in coverage and uniform in film formation.

Description

technical field [0001] The invention relates to the field of oil solvents, in particular to a novel anti-rust oil, and also relates to a preparation method of the novel anti-rust oil. Background technique [0002] Anti-rust oil is a kind of reddish-brown oil solvent with anti-rust function. It is composed of oil-soluble corrosion inhibitor, base oil and several auxiliary additives. According to performance and use, anti-rust oil is divided into fingerprint removal type, Water-diluted type, solvent-diluted type, anti-rust and lubricating type, sealed anti-rust type, replacement type, anti-rust grease type and gas phase anti-rust and other types, anti-rust oil is widely used in metal anti-corrosion treatment to prevent rust to reduce losses. [0003] The presence of free acid in the traditional anti-rust oil reduces the anti-rust performance of the anti-rust oil; the concentration of corrosion inhibitor in the oil is low, so that the adsorption layer cannot be closely arrange...

AI Technical Summary

Problems solved by technology

[0003] The presence of free acid in the traditional anti-rust oil reduces the anti-rust performance of the anti-rust oil; the concentration of corrosion inhibitor in the oil is low, so that the adsorption layer cannot be closely arranged, and the corrosion inhibition is low, which affects the anti-rust effect; the composition of the anti-rust oil The coagulation of the film is poor, the oil film is lost and the stability of the film formation is not good when the anti-rust oil is used; the viscosity of the oil is high, the coating is inconvenient and the oil film is thick, and the consumption of the anti-rust oil is large, resulting in poor economic applicability. The high surface tension of the oil results in low leveling and uniformity. The anti-rust oil cannot form a flat, smooth and uniform oil film during the film formation process, and the coverage is poor and the quality of the film formation is low.
